Abstract
The invention discloses a cold heading mold for a brake caliper guide pin, which is used for processing the brake caliper guide pin by means of cold heading molding. The cold heading mold comprises a head mold part and a rod mold part which are molded integrally, wherein a head cavity for molding the head of the caliper guide pin is formed in the head mold part; a rod cavity for molding the rod part of the caliper guide pin is formed in the rod part mold. By adopting the cold heading mold, the straightness and verticality of the caliper guide pin can be effectively controlled in the process of cold heading molding of a fastener blank, and the product quality is ensured.
Description
Technical field
The present invention relates to a kind of cold upsetting die of car, specifically relate to the cold pier mould of a kind of brake callipers guide finger.
Background technology
Clamp guide finger is the important securing member of braking automobile clamp, requirement has very high linearity and perpendicularity, producing brake callipers guide finger adopts cold upsetting die of car to carry out processing and forming conventionally, but, in prior art, the cold upsetting forming die of clamp guide finger is generally Split type die, comprises head mold and bar portion mould.There is product linearity and the unsettled problem of perpendicularity after cold-heading molding in this split type cold upsetting die of car, the linearity of clamp guide finger product and perpendicularity are difficult to control, and have affected the quality of clamp guide finger product.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention proposes the cold pier mould of a kind of brake callipers guide finger, in fastener blank cold-heading molding process, can effectively control linearity and the perpendicularity of clamp guide finger, ensures product quality.
Technical scheme of the present invention is achieved in that
The cold pier mould of a kind of brake callipers guide finger, for cold-heading molding processing brake callipers guide finger, described cold upsetting die of car comprises head mold portion and the bar portion mold of integrated molding, in described head mold portion, be provided with the head cavity for moulding clamp guide finger head, in described bar portion mold, be provided with the bar cavities for moulding clamp guiding pin rod portion.
As a further improvement on the present invention, described head mold portion comprises die sleeve and core rod, and described die sleeve cover is fixed in outside described core rod, forms described head cavity in described core rod, and described core rod extends axially in described bar portion mold.
As a further improvement on the present invention, the surface of described head cavity and described bar cavities is the burnishing surface after polishing grinding.
The invention has the beneficial effects as follows: the invention provides the cold pier mould of a kind of brake callipers guide finger, for cold-heading molding processing brake callipers guide finger, split type cold-heading mould compared to existing technology, the present invention is designed to head mold portion and the bar portion mold of integrated molding, form monoblock type cold upsetting die of car, thereby can avoid Split type die cold-heading molding process unstable, have the problem of linearity and perpendicularity.In addition, process formation burnishing surface by the surface of head cavity and bar cavities being carried out to polishing technology, can further improve the smoothness of clamp guide finger product after cold-heading molding, make the product after cold-heading molding be not easy to produce burr, and can reduce the damage of burr to monolithic mold, improve the life-span of monolithic mold.
Brief description of the drawings
Fig. 1 is the cold pier mould structure of brake callipers guide finger of the present invention schematic diagram.
By reference to the accompanying drawings, make the following instructions:
1---head mold portion 2---bar portion mold
11---head cavity 21---bar cavities
12---die sleeve 13---core rod
Detailed description of the invention
As shown in Figure 1, the cold pier mould of a kind of brake callipers guide finger, for cold-heading molding processing brake callipers guide finger, described cold upsetting die of car comprises head mold portion 1 and the bar portion mold 2 of integrated molding, in described head mold portion, be provided with the head cavity 11 for moulding clamp guide finger head, in described bar portion mold, be provided with the bar cavities 21 for the bar portion of moulding clamp guide finger.The linearity of brake callipers guide finger and perpendicularity have directly affected the quality of this product, relatively split type cold upsetting die of car, head mold portion of the present invention and bar portion mold integrated molding, the monolithic mold forming, can effectively control linearity and perpendicularity that the cold-heading of brake callipers guide finger adds man-hour, ensure the quality of product.
Preferably, described head mold portion comprises die sleeve 12 and core rod 13, and described die sleeve cover is fixed in outside described core rod, forms described head cavity in described core rod, and described core rod extends axially in described bar portion mold.According to the needs of cold-heading processing, core rod can adopt the larger material of relative die sleeve hardness, to meet the cold-heading molding needs of clamp guide finger head.
Preferably, the surface of described head cavity and described bar cavities is the burnishing surface after polishing grinding.Adopt polishing technology to carry out polishing to head cavity and bar cavities, can further improve the smoothness of clamp guide finger product after cold-heading molding, make the product after cold-heading molding be not easy to produce burr, and can reduce the damage of burr to monolithic mold, in the service life of improving monolithic mold, save production cost.
Above embodiment is with reference to accompanying drawing, to a preferred embodiment of the present invention will be described in detail.Those skilled in the art is by above-described embodiment being carried out to amendment or the change on various forms, but do not deviate from the situation of essence of the present invention, within all dropping on protection scope of the present invention.
